Design: Instrument development and inter‐rater reliability (IRR) assessment. Method: NEOLCAT was constructed from patient care items obtained from clinical guidelines and literature on end‐of‐life care. Expert clinicians reviewed the items. Using percentage agreement and Fleiss' kappa we calculated IRR on 32 nominal items, out of 76 items. Results: IRR of NEOLCAT showed 89% (range 83%–95%) overall categorical percentage agreement. The Fleiss' kappa categorical coefficient was 0.84 (range 0.71–0.91). There was fair or moderate agreement on six items, and moderate or almost perfect agreement on 26 items. Conclusion: The NEOLCAT shows promising psychometric properties for studying clinical components of care of neurological patients at the end‐of‐life on an acute hospital ward but could be further developed in future studies.Licence for VoR version of this article: http://creativecommons.org/licenses/by/4.0/© 2023 The Authors.
